On CNN's The Situation Room on Thursday, host Wolf Blitzer asked Gingrich if Romney is a liar.
"I still believe that the Romney campaign said things that weren't true," Gingrich said.
Gingrich, who suspended his campaign on Wednesday after winning just two states of South Carolina and his home state of Georgia, has called Romney a liar in the past. In an interview
"I just think he ought to be honest with the American people and try to win as the real Mitt Romney, not try to invent a poll-driven, consultant-guided version that goes around with talking points, and I think he ought to be candid. I don't think he's being candid and that will be a major issue," Gingrich said on CBS News after Mitt Romney and a pro-Romney independent group pounded Gingrich with negative television advertising ahead of the Iowa caucus.
Despite Gingrich's statements on CNN Thursday, Gingrich said he will support Romney and will campaign for him because he is the best available option.
"This is a comparative business. And our choice isn't Mitt Romney or Ronald Reagan," Gingrich said, repeating similar sentiments during his suspension speech.
"I said I'm going to campaign for him. I said he will appoint dramatically better judges than the president. He'll do a dramatically better job creating jobs than the president. He'll do far more to balance the budget than the president," Gingrich told Blitzer.
